She remained at Harrison's Landing until the 12th of August, and passed through all the terrible and trying scenes that attended the arrival of the defeated, demoralized, and depressed troops of McClellan's army. These baffle description. Enough, that hands and heart were full—full of work, and full of sympathy, with so much frightful suffering all around her! She was here greatly aided and sustained by the presence and help of that excellent man, Chaplain Arthur B. Fuller, who passed away to his reward long ere the close of the struggle, into which he had entered with so true an appreciation and devotion. Again, here as everywhere, gratitude for kindness, and cheerfulness in suffering marked the conduct of the poor men under her care.
When the army left she repaired again to Fortress Monroe, and was on duty there at Hygeia Hospital during the transit of the army.
She returned to Alexandria the 30th of August, and almost immediately heard rumors of the fighting going on at the front. She applied for permission to proceed to the field, but was informed that the army was retreating. The next tidings was of the second battle of Bull Run, and the other disastrous conflicts of Pope's campaign. As she could not go to the front to give aid and comfort to that small but heroic army in its retreat she did what she could for the relief of any sufferers who came under her notice, until the news of the conflict at Antietam was received, with rumors of its dreadful slaughter. Her heart was fired with anxiety to proceed thither, but permission was again denied her, the surgeon-general replying that she was evidently worn out and must rest for a time. He was right, for on the ensuing day she was seized with a severe illness which prevented any further exertion for many weeks.
During the slow hours of convalescence from this illness she revolved a plan for systematizing the female branch of the relief service. Her idea was to provide a home for volunteer nurses, where they could be patiently educated and instructed in the necessities of the work they were to assume, and where they could retire for rest when needed, or in the brief intervals of their labors.
Her first labor on recovery was to proceed to Warrenton with supplies, but she found the army moving and the sick already on board the cars. She did what was possible for them under the circumstances. The trains moved off and she was left to wait for one that was to convey her back to Alexandria. This, however, was cut off by the rebels, and she found herself with no resource but to proceed with the army to Acquia Creek. She records that she reached Acquia, after several days, and a new and interesting experience, which was kindness and courtesy from all with whom she came in contact.
Immediately after her return to Washington, Mrs. Edson attempted to systematize her plan for a home and training school for nurses. A society was formed, and Mrs. Caleb B. Smith at first (but soon after in consequence of her resignation) Mrs. B. F. Wade, was appointed President, and Mrs. Edson, Secretary.
Many meetings were held. The attention of commanding and medical officers was drawn to the plan. Almost unanimously they expressed approval of it.
Mrs. Edson was the soul of the work, hers was the guiding brain, the active hand, and as is usual in similar cases most of the labor fell upon her. She visited the army at Fredericksburg, and carefully examined the hospitals to ascertain their needs in this respect. This with other journeys of the same kind occupied a considerable portion of the winter.
State Relief Societies had been consulted and approved the plan. Mrs. Edson visited the Sanitary Commission and laid the plan before them, but while they admitted the necessity of a home and place of rest for nurses, which they soon after established, they regarded a training school for them unnecessary, believing that those who were adapted to their work would best acquire the needed skill in it in the hospital itself, and that their imperative need of attendants in the hospitals and in the departments of special and field relief, did not admit of the delay required to educate nurses for the service.
The surgeon-general, though at first favorably impressed with the idea, on more mature consideration discouraged it, and withheld his approval before the Senate Committee, who had a bill before them for the establishment of such an institution. Thus thwarted in the prosecution of the plan on which she had set her heart, Mrs. Edson did not give up in despair, nor did she suffer her sympathy and zeal in its prosecution to prevent her from engaging in what she rightly regarded as the paramount work of every loyal woman who could enter upon it, the care of the sick and wounded after the great battles. The fearfully disastrous battle of Fredericksburg in December, 1862, called her to the front, and she was for several weeks at Falmouth caring tenderly for the wounded heroes there. This good work accomplished she returned to Washington, and thence visited New York city, and made earnest endeavors to enlist the aid of the wealthy and patriotic in this movement. She was familiar with Masonic literature and with the spirit of Masonry. Her husband had been an advanced member of the Order, and she had herself taken all the "Adoptive Degrees." These reasons induced her to seek the aid of the Order, and she was pleased to find that she met with much encouragement. The "Army Nurses' Association" was formed in New York, and commenced work under the auspices of the Masons. In the spring of 1864, when Grant's campaign commenced with the terrible battles of the Wilderness, Mrs. Edson hastened to the "front." Almost immediately the surgeons requested her to send for ten of the nurses then receiving instruction as part of her class at Clinton Hall, New York.
